Meanwhile, Shadow is seen running down a corridor towards Cosmo's room. The security system comes on just in time to reveal Shadow's presence. Chris arrives on the scene to have Shadow fire a Chaos Spear at him. At the last moment, Sonic rescues Chris and takes the blow. Before Shadow gets a chance to attack Cosmo, Sonic gets back up and gets into a scuffle with him. Sonic tells Tails to run away with Cosmo. As they get out of there, Sonic gets knocked to the ground by Shadow and passes out.

However, Tails and Cosmo escape again into the air duct. Shadow follows them, but Tails reaches the top first and hits the shut down button, temporarily trapping Shadow in there with the lasers. Before Tails can move a couple of feet though, Shadow spin dashes through the ceiling and prepares for an attack. Knuckles arrives and tries to stop Shadow, claiming he always wanted to shadow box. Knuckles gets beaten down by Shadow, but managed to stall him long enough for Tails and Cosmo to escape, and left with Rouge.

After running for a while longer, Tails and Cosmo are cornered in a dead end and Shadow insists that Tails gives him Cosmo, but he refuses and pulls a lever behind him that traps Shadow inside the Sonic Power Cannon. The hedgehog is shoot off into space, but reappears via Chaos Control of which the emerald disintegrates, revealing it to be a fake. Shadow claims he does not want to hurt Tails, then walks toward a terrified Cosmo, saying "All right, let's get this over with." As he is about to kill Cosmo, Tails tried to stop Shadow by grabbing his leg but is severely wounded. Then just as Shadow was about to use Chaos Spear on Cosmo and Tails, the Metarex appears and reveals to everyone that Cosmo is a spy, she has a codename White Seed and they monitor what she hears and sees through some kind of device implanted in her brain. Cosmo's amulet shines and she screams. A white light surrounds The Blue Typhoon, making it disappear, and the episode ends on a cliff hanger.
